n/zPRovnn APPARATUS r'oR.DnonoRrzrNG, DESIGCATING, AND MIXING MArrcrRns.

The Schedule referred to in these Letters Patent andmaking part of the same.

Be it known that I", HENRY S. FIRMAR, of the city, county, and State of New York, have invented a certain new and useful Apparatus for Desiccating, De-

odorizing, and Mixing Mannres, or other similar .com-v the heat is generated to dry the mixture; and, second, of a pan, in which the material is dried and mixed; and,

third, oi' a hopper, by which the material is introduced intp the pan; and, fourth, of a series 'of mixers, prop erly connected,'and operated to stir and mix the materials as the drying proceeds.

To enable others skilled in the arts to which my invention appertains, to make and use the same, I will proceed to describe the construction of these various parts, and the relation they occupy to each other, and also their mode of operation.

In the drawing, theA desiccating and mixing-pan is represented by A3 It is an air-tight vessel, composed of boiler-iron, duly riveted and caulked, and formed in about the shape represented by the drawing. Y

This pan is set in a chamber, composed of brickwork, made larger in its length and breadth, by about one foot, than the pan, and about six inches deeper than the main body of said pan, leaving aue under the bottom and'on Iall sides of it, in the manner substantially as shown; the pan being supported on the top of the brick-Work, by means of iianges riveted around the outside thereof, and arranged to lap over on the brick-work to form a top or cover to the flue around the pan.

In the bottom of this brick chamber, a urnace, F, is formed, covered with an arch, and arranged with ilues, P, radiating from the foot or heel of the arch, and which ilues are covered with dampers, l, to reguf late the admission of heat' from the furnace to the chamber in which the pan is set; the handles, Z, of said dampers being made to reach to the outside of the wall, to facilitate their adjustment.

To keep the heat or ame from ascending directly om the 'furnace against the bottom of the desiccatingpan, and burning the material treated, I arrange directly over the tlues ofthe furnace an iron plate, Q, with a series oi' peribrated holes, k, to be made therein, a little inside or out of the line of the furnace-ues, to break the force and direction of the ascending current of hot air from the furnace, and keep it from impinging in a given spot against the bottom of the pan.

To stir and mix the material to bev treated in the projecting rods, d d d, made long enough to reach to the bottom of the pan, or nearly so, leaving them free to vibrate to and o over the bottom of the pan, which is curved on the arc struck by each of these rods, in E themanner shown.

The aforesaidshaits and rods being made and arrangedvas above set'forth, 'I connect them together by means of connecting-rods e c and levers b b, arranged substantially iu the manner shown, connecting one of the end-shafts to the reciprocating rod c, by means of a link, a, by which means all these mixers are made to vibrate at one time in opposite directions, by the` application of power to said reciprocating rod, thus constantly moving and mixing the material contained in the pan, and-thoroughly incorporating the diiierent elements with each other. v

After the material has been suiiciently treated, it is removed from the pan through gates E E, of which there are three on each side, or on one side, asthe case may require, said gatesbeing fitted with suitable covers or doors to make them impervious to the air, and said pan is also iitted with lights of glass, j, through which the treatment of the material -may be inspected from time to. time, as the operation proceeds.

The material to be treated is introduced into the pan through the hopper R, into the box P, fitted with sloping bottoms, q, which direct the material to the hoppers o and through the valves n, which are arranged to open and close at the will of the attendant; vthe hoppers o being also fitted with steam-tight valves, fm., to prevent the escape of the oensive gases from the pan after it has been charged The pan is also fitted with a pipe, J, connected to branch-pipes i and g, the object of which pipesis to create a circulation of the air and gas in the pan, through the agency of an ordinary air-pump attached to the pipe g, the said pipes being iitted with suitable receiving and delivering-valves, to insure the proper operation of the pump.

In connection with the desiccating or mixing-pan, there is a box, S, arranged in some suitable position, and which is also fitted with a false bottom, t, and connected to the pan by means of a pipe, u, for the purpose ofcarrying the unabsorbed gases from the pan to this chamber or box, which is to be charged with some suitable absorbent to' take up the gases aforesaid, said box being also tted with a Waste-pipe, e, to carry off any water of condensation that may accumulate in the bottom of the chamber.

Now, the object of this invention is to manufacture making the establishment a nuisance in which the manu facture is carried on, which object is accomplished by abscrbing and utilizing the gases in the material while in an air-tight vessel, thus saving the gases, and avoiding the nuisance, by means of the apparatus yabove described7 and illustrated in the accompanying drawing.

Having now described the construction and operation of my said apparatus,

I claim as new herein, and desire to secure by Letters Patentl. Arran gin g a close desiccating and mixing-pau, con structed substantially in the manuel' described, and provided With mixers7 as set forth, in a close heating-chamber7 'over a furnace or heating-flue fitted with dampers, and constructed substantially as described.

2. The combination ofthe supply-hopper, constructed substantially as desciibedmith a close desiccating-pan, for the purpose of introducing the material to be treated in the pan, as set forth.

3. Combining, With a close desiccating and mixingpan7 a deodorizing or absorbing-chamber, for the purpose of utilizing the oi'ensive gases, and avoiding the nuisance occasioned by their escape from the pan.

.4. Creating a circulation of the aix' and gas inthe desiccating-pan by means of an air-pump afxed thereto, through the agency of pipes arranged substantially as described.
